head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
A modern-war reboot following Tier 1 operators in Afghanistan.

Execution · Practiced Mastery
Planning approaches with recon tools, then executing them under lethal fire.
Medal of Honor (2010) leans Execution (Practiced Mastery); Tom Clancy's Ghost Recon Advanced Warfighter leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor (2010)
Modern gunplay in campaign and multiplayer
Tom Clancy's Ghost Recon Advanced Warfighter
Lethal firefights punish sloppy aim and exposure
Tom Clancy's Ghost Recon Advanced Warfighter leans a little harder on reads, though the gap is small.
Medal of Honor (2010)
Competitive MP adds human prediction
Tom Clancy's Ghost Recon Advanced Warfighter
Multiplayer squads outflank and adapt to your habits
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Medal of Honor (2010)
Scripted campaign, modest MP randomness
Tom Clancy's Ghost Recon Advanced Warfighter
Enemy placements are scripted-but-unknown on first attempt
Tom Clancy's Ghost Recon Advanced Warfighter leans a little harder on optimization, though the gap is small.
Medal of Honor (2010)
Loadouts and map control are learnable
Tom Clancy's Ghost Recon Advanced Warfighter
Drone recon, squad orders and approach planning decide missions
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
